The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, an embodiment of the present invention provides an electric pressure cooker 100, which includes a cooker body 10 and a cooker cover 20, wherein the cooker cover 20 covers the cooker body 10 and defines a cooking space with the cooker body 10 for cooking food.
Referring to fig. 2, specifically, the pan body 10 includes a base 11, an outer pan 12, and an inner pan 13, wherein one end of the outer pan 12 is coupled to the base 11, and the other end extends away from the base 11 to define a receiving cavity with an opening with the base 11, and the inner pan 13 is received in the receiving cavity from the opening. The cover 20 is covered on the outer pot 12 and forms the cooking space with the inner pot 13. The base 11 is provided with a heating mechanism 112 for heating food in the cooking space, and the cover 20 is provided with a pressure release valve 21 for releasing pressure in the cooking space.
Wherein at least a portion of the outer pot 12 is controllably separated from the pot cover 20 and/or the base 11 to form a communication port 50 (see fig. 3) communicating between the outside and the inner pot 13.
Through the above arrangement, after the electric pressure cooker 100 finishes cooking, at least part of the outer cooker 12 can be separated from the cooker cover 20 and/or the base 11, so as to form the communication port 50 communicated between the outside and the inner cooker 13, and the outside air flows to the inner cooker 13 through the communication port 50 and exchanges heat with the surface of the inner cooker 13 (i.e. the whole indoor environment reduces heat for the inner cooker 13). In this way, when the temperature in the inner pot 13 is reduced, the pressure in the inner pot 13 is correspondingly reduced, and when the pressure in the inner pot 13 is reduced, the time required for pressure relief is shortened, so that the time required from the end of cooking to the consumption is saved.
In one embodiment, portions of the outer pot 12 are controllably separated from the pot cover 20 and/or the base 11. Specifically, the outer pot 12 includes at least two connection blocks that are independently disposed, and all the connection blocks are butted to form the outer pot 12. Referring to fig. 4 and 5, a part of the connection blocks are divided into first connection blocks 121, and the rest of the connection blocks are divided into second connection blocks 122, wherein the first connection blocks 121 are controllably separated from the pot cover 20 and/or the base 11, and the second connection blocks 122 are connected between the base 11 and the pot cover 20.
Referring to fig. 3, after cooking is completed, the first connection block 121 may be separated from the lid 20 and/or the base 11 to form the communication port 50 communicating between the outside and the inner pot 13. The second connecting block 122 is always connected between the base 11 and the pot cover 20 to prevent the pot cover 20 from being washed away by excessive pressure in the inner pot 13.
It will be appreciated that in other embodiments, it is also possible to provide that all of the outer pot 12 is separate from the pot cover 20 and/or the base 11. As in one embodiment, the whole of the outer pot 12 is controllably separated from the pot cover 20, and the whole of the outer pot 12 can be separated from the pot cover 20 after cooking is finished, but it is necessary that the electric pressure cooker 100 further comprises a connection mechanism, and the connection mechanism is controlled to be connected between the base 11 and the pot cover 20 before the whole of the outer pot 12 is separated from the pot cover 20, so as to prevent the pot cover 20 from being washed open under the action of high pressure. In another embodiment, the whole outer pot 12 is separated from the base 11, and when cooking is finished, the whole outer pot 12 can be separated from the base 11, and the electric pressure cooker 100 also needs to comprise a connecting mechanism, and before the whole outer pot 12 is separated from the base 11, the connecting mechanism is controlled to be connected between the base 11 and the cooker cover 20, so as to prevent the cooker cover 20 from being flushed under the action of high pressure. In still another embodiment, the outer cooker 12 is entirely separated from the cooker cover 20 and the base 11, and the electric pressure cooker 100 also includes a connection mechanism, which is controlled to be connected between the base 11 and the cooker cover 20 before the outer cooker 12 is entirely separated from one of the cooker cover 20 and the base 11, so as to prevent the cooker cover 20 from being opened under high pressure.
Specifically, the first connection block 121 is slidably coupled to the base 11 and controllably slides with respect to the base 11 in a direction away from the inner pot 13 such that the other end of the first connection block 121 is separated from the pot cover 20 to form the communication port 50.
With continued reference to fig. 2, in one embodiment, the electric pressure cooker 100 further includes a movable member 30, the base 11 is provided with a chute 111, the movable member 30 is slidably disposed in the chute 111, the first connecting block 121 is slidably connected with the base 11 through the movable member 30, and the movable member 30 controllably slides in the chute 111 to drive the first connecting block 121 to move in a direction away from the inner cooker 13, so as to separate the outer cooker 12 from the cooker cover 20. It is conceivable that in another embodiment, the movable member 30 may be omitted from the electric pressure cooker 100, the base 11 is provided with the sliding groove 111, the first connecting block 121 is directly slidably disposed in the sliding groove 111, and the first connecting block 121 controllably slides in the sliding groove 111 to move in a direction away from the inner pot 13, so that the other end of the first connecting block 121 is separated from the pot cover 20 to form the communication port 50.
Specifically, the electric pressure cooker 100 includes a control mechanism and a driving mechanism, the driving mechanism is connected to the control mechanism, and the movable member 30 is connected to the driving mechanism. The base 1111 has an operation panel 40, and the operation panel 40 is electrically connected to the control mechanism. When the cooking is finished, the operation panel 40 can be operated, so that the control mechanism controls the driving mechanism to act, and the driving mechanism drives the movable piece 30 to move in the chute 111 so as to drive the first connecting block 121 to move towards the direction away from the inner pot 13.
In one embodiment, when the first connecting block 121 is separated from the pot cover 20 and then can be rotated and unfolded relative to the base 11, after the first connecting block 121 is unfolded, the communication area of the communication opening 50 formed between the first connecting block 121 and the pot cover 20 is increased, so that more air from the outside can be promoted to enter the inner pot 13 from the communication opening 50 to exchange heat with the outer surface of the inner pot 13. That is, the first connecting block 121 and the second connecting block 122 of the outer pot 12 of the electric pressure cooker 100 provided in the present embodiment are similar to petals of a flower, the first connecting block 121 can be unfolded like petals are in a meeting, and the second connecting block 122 is always connected between the base 11 and the pot cover 20 (see fig. 3).
Referring to fig. 6, specifically, the movable member 30 includes a sliding member 31 and a rotating member 32, the sliding member 31 is slidably disposed in the sliding slot 111, the rotating member 32 is connected to the movable member 30, and the first connecting block 121 is rotatably connected to the rotating member 32. The sliding member 31 controllably slides in the sliding slot 111 to drive the rotating member 32 and the first connecting block 121 to move towards a direction away from the inner pot 13, and the first connecting block 121 can be rotated and unfolded relative to the rotating member 32 after being separated from the pot cover 20.
It is conceivable that in other embodiments, the movable member 30 may be omitted in the electric pressure cooker 100, and instead, a sliding groove and a rotating groove which are communicated with each other are formed in the base 11, and after the first connection block 121 slides from the sliding groove to the rotating groove, the first connection block 121 is separated from the pot cover 20, and the first connection block 121 is rotatably unfolded in the rotating groove.
In one embodiment, the first link 121 may be rotatably unfolded with respect to the rotary member 32 under its own weight. That is, after the upper end of the first connecting block 121 is separated from the restriction of the lid 20, since the lower end of the first connecting block 121 is rotatably connected with the rotating member 32, if the upper end of the first connecting block 121 is heavier than the lower end and the outer side of the upper end is heavier than the inner side, the first connecting block 121 is unfolded by the gravity. It is contemplated that in other embodiments, the upper end of the first connecting block 121 may be controlled by a control mechanism to be unfolded after being separated from the restriction of the pot cover 20, which is not limited herein.
Further, the rotating member 32 is a mounting tube, the mounting hole is formed at one end of the first connecting block 121 connected with the rotating member 32, the mounting tube is arranged in the mounting hole in a penetrating manner, and when the first connecting block 121 is separated from the pot cover 20, the first connecting block 121 can rotate in a matched manner with the mounting tube through the mounting hole.
Referring to fig. 7 and 8, specifically, the mounting tube includes a first semicircular tube 321 and a second semicircular tube 322 that are disposed opposite to each other, the sliding member 31 includes at least two sliding members disposed at intervals, the first semicircular tube 321 is connected to a part of the sliding member 31, and the second semicircular tube 322 is connected to the rest of the sliding member 31. Wherein, part of the first connecting blocks 121 are rotationally connected to the first semicircular tube 321, the rest of the first connecting blocks 121 are rotationally connected to the second semicircular tube 322, the second connecting blocks 122 are connected to the butt joint of the first semicircular tube 321 and the second semicircular tube 322, and the position between the second connecting blocks 122 and the base 11 is unchanged when the first semicircular tube 321 and the second semicircular tube 322 move.
That is, when cooking is completed, the control mechanism controls the sliding member 31 to move in the chute 111, the first semicircular tube 321 and the second semicircular tube 322 which are originally abutted are separated to form an ellipse, at this time, the upper end of the first connecting block 121 is separated from the pot cover 20, and when the upper end of the first connecting block 121 is separated from the restriction of the pot cover 20, the sliding member is unfolded under the action of gravity. Because the second connecting block 122 is connected to the butt joint of the first semicircle tube 321 and the second semicircle tube 322, when the first semicircle tube 321 and the second semicircle tube 322 are separated from each other, the change of the size of the butt joint is small (that is, after the circle is changed into the ellipse, the diameter of the circle is equal to the short axis of the formed ellipse), and the separation of the first semicircle tube 321 and the second semicircle tube 322 will not affect the second connecting block 122, and the second connecting block 122 is still fixed between the base 11 and the pot cover 20.
With continued reference to fig. 3 and 5, in one embodiment, the first connection block 121 includes 6 blocks and the second connection block 122 includes two blocks. When the first semicircle tube 321 and the second semicircle tube 322 are separated from each other, the 6 first connecting blocks 121 can be driven to move in the direction away from the inner pot 13, and when the first connecting blocks 121 move to the upper end to be separated from the pot cover 20, the first connecting blocks are unfolded. When the first semicircle tube 321 and the second semicircle tube 322 are separated from each other, the second connection block 122 does not move relative to the pot cover 20 and the base 11. It will be appreciated that in other embodiments, the first connection block 121 may also be configured to include 4 blocks, and the second connection block 122 may also include 4 blocks, which is not limited herein.
In addition, the first connection block 121 is provided as a telescopic member, and the first connection block 121 is controllably contracted when the first connection block 121 is separated from the pot cover 20. To reduce the occupation of more indoor space after the first connection block 121 is unfolded.
In one embodiment, the electric pressure cooker 100 further includes an auxiliary cooling mechanism (not shown) provided on the base 11 for auxiliary cooling of the inner cooker 13. Specifically, the auxiliary cooling mechanism is filled with a cooling liquid, and the temperature of the inner pan 13 is lowered by exchanging heat between the cooling liquid flowing therein and the surface of the inner pan 13.
More specifically, the auxiliary cooling mechanism has a first position accommodated in the base 11 and a second position extending out of the base 11 with respect to the base 11, and the auxiliary cooling mechanism is switched between the first position and the second position. When cooking, the auxiliary cooling mechanism is at the first position, and after the first connecting block 121 is separated from the pot cover 20, the auxiliary cooling mechanism is at the second position to cool the inner pot 13 together with the external air.
In another embodiment, the electric pressure cooker 100 further includes a heat insulation mechanism provided independently of the cooker body 10 and the cover 20, and when the first connection block 121 is unfolded, the heat insulation mechanism is wrapped outside the inner cooker 13 to prevent the user from touching the inner cooker 13 to be scalded. Specifically, the heat insulation mechanism is a reticular structure with hollowed holes, the hollowed holes allow external air to flow to the inner pot 13 for heat exchange with the surface of the inner pot 13, and the reticular structure can prevent users from being scalded by directly contacting the inner pot 13.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
